Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple quantum bits, or qubits—the fundamental information-storing building blocks of quantum computers.
How so?
I think it will change our perspective on how the quantum realm works. It will be the first true interaction between humans and quantum effects on a daily basis.
Tunneling electron microscopy exists for over 30 or 40 years. That’s a direct application of quantum physics. IBM even famously “reversed the polarity” on one of its sub-10-atoms tip in order to pick and place nitrogen molecules on a flat surface, writing their logo with it. (And proving they could build nano machines.)
